I don't know too much about this, but I went to pick up an antique post office sorting cabinet (of which I will also be posting pics) and the lady who was selling the cabinet asked me if I wanted this poster/picture. Of course I couldn't turn it down with those awesome colors and cool graphics. It is a very heavy chipboard type material and obviously has some water damage, but otherwise I think it's a super-cool piece. She said that her husband was Swedish and they had divorced some time ago. She had tons of cool stuff!
